"She is bound to the south, for we saw her off St. Johns' bar headed in that direction. The pilots off the St. Augustine light saw her to-day noon. We were chasing her when our passengers desired to get out of the heavy sea."

"I should think Colonel Shepard would have some idea of the motives of Captain Blastblow."

"He has no more idea than I have, and I have none. We are inclined to believe that the captain misunderstood his orders, for Colonel Shepard was in doubt whether or not he should be able to go up the Mississippi with us. When the mail got in yesterday afternoon, he wrote a card with his instructions to Captain Blastblow on it, and sent it off to the Islander by Nick Boomsby, who happened to be talking to me in the post-office at the time."

"Sent it off by Nick Boomsby," repeated Cornwood; but he did not appear to be astonished. "How came Nick to be about at that time?"

I told my late guide and pilot all that passed between me and the son of my ancient enemy, to which he listened with deep interest. He seemed to be engaged in earnest thought all the time, as though Nick's movements had some meaning to him, though not a particle to me. I told him I was in Captain Boomsby's saloon to say good-by to him at the time the robbery of the messenger occurred. He questioned me very minutely in regard to the affair, and I told him all I knew about it.

"Buckner sent for me to act as his counsel; but I thought I could make more by coming down here," added Cornwood. "I lost one case a few days ago, and I don't care to lose another yet awhile."

Cornwood laughed as he alluded to his defence of Griffin Leeds, the mulatto employed by him to do his bidding on our excursion to the interior.

"Have you any doubt that Buckner is the man who robbed the messenger of the four thousand dollars?" I asked, rather to bring him out than because I valued his opinion in a detective case.

"Not the slightest in the world; but I should not be surprised to learn that he gave Nick a hundred dollars, or something of that sort, to clear out at just this time," replied Cornwood, easily.

"I don't see how that could have been," I protested. "Nick could not have seen Buckner after the money was stolen, unless he visited him in the lock-up."
